This catch-lever is providedwith the application of these improvements and two lateral arms, 1) E,which unite and carry 5 their construction and operation. a stud, 5,that co-operates with a cam-bar, 4,

5 In the drawings, Figures 1, 2, and S are side the hooked end of whichmay be engaged with elevations. Fig. 1 exhibits the impressionanddisengaged from the stud 5 by means of a cylinder wheel as about toengage with the coupling-bar, 7, whose upper end is pivoted bed rack atthe beginning of the forward to an offset piece, 8, on the jointed endof the travel to produce an impression, the parts he cam-bar 4.

This shaft 1 carries cams 2 and 3, oneupon each side of the stock F of the cam-bar 4, which cams respectivelybear upon friction-rolls 40 41, carried by said stock F. The catch-leverO carries another stud, 13, which co-operates with a hook edlocking-arm, 14, that is pivoted to the framework,and operated by meansof the couplingbar 7 through a rod, 15, pivoted at one end to the arm 14and at the other to the bar 7. This rock-shaft 9 may be moved by ahand-lever, 16, keyed to its outer end. Upon moving this lever to theleft the shaft 9 is rocked and causes the cam 10 to lift the bar 7 andconnectingrod 15, thus lifting the cam-bar4 from off the stud 5 andraising the arm 14 so that its hooked end grasps the stud 13. The lever0, then engaged with the cylinder, is thus coupled to the arm 14,and theactuating cam bar 4 is uncoupled from the arm E of the lever O, as inFig. 3, thereby locking the lever and cylinder stationary and leavingthe crank-shaft 1, the cams 2 3, bar 4, and the type-bed free tocontinue the movements to distribute the ink, or for other purposes, aslong as is desired, as in inking up.

When it is desired to have the cylinder cooperate with each forward runof the typebed, the hand-lever 16 is moved to the right, as in Fig.1,which causes the cam to draw the hooked arm 14 out of engagement withthe stud 13 and the cam-bar 4 down until its hooked end engages with thestud 5. The catch-lever O is thus unlocked from the frame and is free tomove, and, being coupled to the cam-bar 4, will be vibrated through thereciprocation of the bar 4 by means of the cams 2 3, to cause theimpression-cylinder to co-opcrate with the bed at each forward stroke ofthe latter, as in single inking.

To provide for double inking, by causing the impression-cylinder tocooperate with the bed at its alternate forward runs an automatic meansfor properly rocking the shaft 9, and thus coupling anduncoupling thecatch-lever G at proper intervals, is provided as follows: Therock-shaft 9 is provided with a leverclutch, 22, which turns loosely onthe shaft, and said lever-clutch is connected by a rod, 21, with acrank-pin, 20, carried by a wheel,

' 18, on shaft 19, which wheel gears with a pinion, 17, of half its sizeon the crank-shaft 1, said leverclutch thus being rocked once back andforth at each second revolution of the shaft 1. The companion clutch 23slides on the shaftflandits feather24, and when coupled with them theclutch 22 will impart to the shaft 9and its cam 10a rocking motion,whichwill engage and disengage "the cam-bar 4 and arm 14 with and from thecatch-lever Cthrough the coupling-bar 7 and connecting-rod 15, ashereinbefore described with reference to the hand-lever 16.

The recesses in the cam-bar 4 and arm 14 are of such a depth that duringthe operation of changing the one does not let go of the lever C untilafter the other has grasped it, thus keeping the lever always undercontrol.

As the wheel 18 makes but one revolution to two complete runs of thetype-bed, it follows that the impression-cylinder will co-opcrate witheach alternate run of the bed and remain stationary during theintermediate runs, thus causing the form to be inked twice to eachimpression.

To connect and disconnect the clutches 22 and 23, the latter is movedback and forth by means of a rod, 25, which carries a forked arm, 26,that enters into a groove in the clutch. This rod 25 extends outwardthrough the framework and' has a half-circle guard, 27, on its outer endoutside of the hand-lever l6, and

this guard serves to hold the hand-lever 16 in both its right-handand'left-hand positions by means of the locking-screws 28 29, the pointsof which enter a hole in the lever.

When it is desired to make the cylinder cooperative with the alternateforward runs of the bed, the rod 25 is pulled outward, thus firstdrawing the point of the lockingscrew out of the hand-lever 16, which isthus set free, and next draws the sliding clutch 23 into worlv ingcontact with the rocking clutch 22, as in Fig. 5, by which thecatch-lever C will bring the cylinder in and out of operation with thealternate runs of the bed, as has been described.

It is only while thebed is making its return run that the cam-bar 4 canbe connected to and disconnected from the catch-lever C, and to preventthis being done at the wrong time when changing by the hand-lever 16, agoverning device for controlling the movements- This is con-- of thehand-lever is provided. structed as follows: A disk, I, is secured tothe outer end of the shaft 19, and it has two sharp-pointed curvedguards, 31 and 32, secured in a circle to its face with a certaininterval, as 33 or 34, between each of them. These guards co-operatewith a bar, 35, one end of which is jointed to the hand-lever 16, whilethe opposite end is forked and embraces the shaft 19, and it hasalozenge-shaped stoppiece, 36, fixed on its side next to the curvedguards 31 32 in such a position that when the hand-lever 16 is turned toits right-hand position the piece 36 will be outside the path of theguards, and when the lever is in its left-hand position the piece 36will be inside the path of the guards. It is obvious from this that thelever 16 cannot be turned from one position to the other to connect anddisconnect the. cam-bar4from the catch-lever 0, except at such times aswhen a space, 33 or 34, between the curved guards is in front of thepiece 36,

and the curved guards are so placed that one of the spaces 33 or 34 isin front of the piece 36 only when the bed is making its backward run.If by chance the hand-lever should be left in a midway position with thecam-bar 4, and the recessed arm 14 both grasping the catch-lever O, thecurved guards 31 or 32 would strike the piece 36 on the bar 35 andcomplete either the engagement or disengagement of the catch-lever C. Bythis simple mechanism a movement of the hand-lever 16 to the right willcause the coupling-bar 7 to hold the cam-bar 4 coupled with thecatch-lever O, and hence the cylinder and bed will cooperate at eachforward run of the latter. By moving the hand-lever to the left thecoupling-bar will disengage the cam-bar 4 from the catch-lever O, andhence no movement of the cylinder will occur. By sliding the rod 25outward the shaft 9 is clutched to the lever 22, and receives a rockingmotion, properly timed by means of the proportion of the wheels 17 18 tocause the coupling-bar 7 to couple and uncouple the cam-bar andcatch-lever at proper times, and thus engage the cylinder-wheel andbed-rack at alternate forward runs of the bed, in the latter adjustmentthe guard 27 being removed so as to leavethe handlever 16 free tooscilate back and forth.

The fly-lever 90 and its lockinglever 91 and the cam 92 are illustratedherein simply to show their relation to the other mechanisms.
